To aZZ whom it may concern:

Be it known that ILJEiionYv J. lnrrs, a citizen of the United states, residing at borough of Fountain Hill, in the county of 5 Lehigh and State of Pennsylvania,,haveinusual to employer flyer which surmountsthe lower or uprightboblvin and is freely rotatlve on its spindle, 1ts function being to keep the yarn lncontrol and also to presists of acentral Wood piece and arms projecting therefrom formed of wire, one of which is provided with an eyelet to form a guide for the yarn. The wires become bent and distorted and their eyelets out by the yarn and these not only seriously affect the spinning operation, especially as they cause thetension on the yarn to be always an uncertain quantity, but they necessitate constock of flyers to keep them in order, so that while the expense of an individual flyer is trifling the expense of upkeep and renewalfrom time to time of the whole equipment of flyers is very considerable runnin-g into thousands of dollars per year in a plant of appreciable size. 7'

My objectis to reduce to the minimum both the initial and upkeep costof the means for keeping the yarn in control and under tension; to provide means having these functions whereby the tension may be readily altered as to any spinning unit according to the strength, size or other qualities of the yarn to be spun; to construct-such means so v as to prevent the working downward of the twist from the upper or receiving bobbin to the lower or upright or delivery bobbin sufiiciently for projecting fibres ofthe yarn on the latter bobbin to become caught in such twist and result in breakage of the yarn, thus niaking it possible to spin at high speed crepe or other high twisted ya-rnsyand to insure that the tension, once predetermined according to the size, strength or other quality vo1": the yarn, shalli remain constant at a given spinning spee i x a To these ends my invention contemplates serve tension on' the yarn. It usually constant care and attention being given to the.

providing the lower or upright bobbin with a race, preferably surmounting the same and arranged concentric with its axis, and arranging on said race, to be guided thereby around the same, a traveler which aflfords a guide or eyelet for the yarn. In the best form therace is ail'orded by a ring preferably of hard polished steel and flanged (as T-sha ied in cross-section) at the top to aiiiord the race proper, and the traveler is a light split ring which arches the race proper, and has its ends engaged under'its flangeprojections". But in addition there is also preferably a peripheral contact surface for the yarn below the race proper which, though smooth, opposes friction and hence a certain degree of resistance tothe travel of the yarn therearound necessary in 0b taining constant tension on theyarn and limiting the progress of the' twist downward. This surface. is best formed by the peripheryof a separate layer or disk of fibre or some other hard smooth substance which is interposed between the end of the bobbin barrel and the metal race.

' In the drawing, v I

Fig. l is a front elevation of sufficient of a spinning unit embodying my invention to illustrate the same; and I Fig. '2 is a vertical sectional. view, partly in elevation, of the delivery wound package equipped with the parts which go to make up the invention. 7 i

a is the lower or upright spindle for driving the lower or delivery package, it being adaptedto be rotated by any means.

7) is the upper bobbin adapted to be rotated on a horizontal. axis andbeing for this purpose suitably .journaled as. in brackets 0 and suitably rotated as by the driving wheel d on which it rests; in the rotation of the bobbin 6 the spun yarn is 'wound thereon and forms a wound package, thewindings being laid on in regular layers by. the reciprocating of a thread guide e carried by a traverse rail 7, all as usual. 9 is a fixed guide through whichthe yarn extends from the delivery package to the guide I In the following description of the parts involved in my invention I follow the construction as it is shown in the accompanying drawing, but it will be understood'that changes. in this construction may be efn at fected without departing from the invention: The delivery spool or bobbin has a barrel 7L and upper and lower disks or heads i and j which are secured to the ends of the barrel by screws Zr. Surmounting the disk or head 2' is another disk Z. Usually the disks 2' and j are composed of fibre; the disk Z I preferably form of wood. Disk Z is held in place on the upper disk 2' by the screws 76, and it has a center hole to receive the spindle and is concentric with respect to the disk. Fitted over the disk Z with a snug fit is a ring of hard polished steel m, which is T-shaped in cross-section. It is held to the disk Z by radial pins 01,; its flange is spaced from the disk Z. It affords the hereinbefore mentioned race, its top portion forming the race proper. On this race is a traveler 0 which is a split ring which arches the race proper and has its ends engaged under the flange-projections thereof. The yarn is indicated at A, and it will be noted that it extends through the traveler and also that the diameter of the disk 21 is such that at least when the spinning is proceeding the yarn bears against the periphery of the disk 1'.

I am aware that in certain yarn operations a traveler receiving the yarn is arranged on a circular race extending around the axis of the windings, one of the parts (usually the package) rotating independently of the other. This, however, is a construction essentially different from my own, which involves placing the race with its traveler directly on so as to rotate with the delivery bobbin in a spinning unit of the class indicated, whereby the usual flyer, with the initial and upkeep expense thereof, is eliminated, and much better results as to tension and reduction of yarn breakage ensue. In the case mentioned, moreover, there is no such surface as that afforded by the periphery of disk i of my invention, opposing frictional resistance to the yarn which is substantially constant in character and preventing working downward of the twist past it.

My object in using a hard surface, as of steel, for the race is not only to adapt it to withstand the wear of the traveler but to avoid possibility of the same becoming dented or burred or in any way marred in handling. Because I avoid the twist working downward into dangerous proximity to the projecting fibres of the delivery pack age I can put a high twist in the yarn in a single operation and at the heretofore impossible speed of 11,000 R. P. M. of the delivery package; and if the surface of the race could be in the slightest degree roughened by a blow it would interfere with the uniform slipping progress of the traveler and stop the operation by breakage of the yarn, even at a lesser speed. The

surface of the race is preferably so hard that it is brittle, whereby it both withstands the wear of the traveler and resists marring. Any dents or other irregularities that might be produced in the peripheral surface of the relatively softer material of the disk 2' and cause breakage are readily eradicable by a smoothing operation.

The structure including the flange-forming head i for the bobbin and the disk Z is made in two parts so that, whereas the head is desirably of fibre, the disk 2' is of a softer material better adapted for the Ii ting thereto of the race.

Having thus fully described my invention what I claim and desire to secure by Letters Patent is:

1. A yarn spinning unit of the class spec fied including, in combination, a rotating support having the windings to be delivered wound around its axis of rotation and having at the delivery end of the mass of wind ings an endless race formed around said axis, and a traveler adapted to receive and guide the delivered portion of the yarn and operatively connected with the race and free to slip around the same continuously, said support also having at said end of the mass of windings a smooth peripheral contact surface substantially concentric with said axis and around which said delivered portion of the yarn is held bent and in wiping contact therewith.

2. A yarn spinning unit of the class specified including, in combination, a rotating support having the windings to be delivered wound around its axis of rotation and having at the delivery end of the mass of windings an endless race formed around said axis, and a traveler adapted to receive and guide the delivered portion of the yarn and operatively connected with the race and free to slip around the same continuously, said support also having between said end of the mass of windings and the race a smooth peripheral contact surface substantially concentric with said and around which. said delivered portion of the yarn is held bent and in wiping contact therewith.

3. A yarn spinning unit of the class specified including, in combination. a rotating support having the windings to be delivered wound around its axis of rotation and having at the delivery end of the mass of windings an endless race formed around said axis, and provided endlessly thereof with a brittle smooth metallic guiding surface, and a traveler adapted to receive and guide the delivered portion of the yarn and operatively connected with the race and free to slip around the same continuously in contact with its said surface, said support also having atsaid end of the mass of windings a smooth peripheral non-metallic contact surface substantially concentric with said axis and around which said delivered and guide the delivered portion of the yarn and operatively connected With and free to slip around the race continuously.

5. A bobbin of the class specified includ ing a barrel, a flange-forming structure for the barrel secured on one end thereof and having a central upstanding boss, and an endless race embracing and held on the boss and adapted to receive and guide endlessly thereof a yarn traveler.

In testimony whereof I affix my signature.
